Washed out colors in game

I created a simple sign and got it in the game with the right colors, but they're washed out with too much of a glossy appearance. I've tried changing the roughness shade and a specular as well, but nothing really changes. I'm using a metalness workflow, for reference.

Here's an image. Overall the actual color is fine, it's just the glossiness aspect that's off. Also, the weird border on the blue sections is something I can't figure out but I'd assume it has to do with the glossiness issue as well.
Ignore the weird "C" as that's an easy fix I'm getting around to.

I meant to post the whole thing, like a cap screen of the images in your zip file as Thumbnail for us to see what your package looks like.
Your icon does look like a more contrasty output.... It could be your shading options in blender... or... not sure....
